I added up the rifles I have used to kill moose and remember an even dozen and they have worn a bunch of different scopes. My first was a small bull at about 40 feet and a 22lr at the base of the ear was adequate. Irons...

About six years ago I started in on a 30-06 and have not looked back since. It has a Vortex Viper PST 4-16x44 on it though it has had several other scopes during the time.

Mark Begich, Joaquin Jackson, and Heller resistance... Three huge reasons to worry about the NRA.
